My main concern is, how long is it before you can't print a replacement part for something you bought because it looks too similar to an OEM part and the manufacturer doesn't think you should be able to do that so they throw a little money to the right politician.
I remember ~10 or 15 years ago, I had concerns about drones becoming illegal due to FAA.
I was assured by the internet, I was paranoid, blah blah safety...
Then a few weeks ago something about Minnesota and ICE making drones illegal to fly or something...
The weird part is that, in that 15 years, I've become more moderate and pro-democratic rule of law... but I was right about my previous concerns. Not that I believe in the Justice behind them anymore.
